Kenjeran waters arecontaminated waters which contain organic and inorganic materials that can degrade the quality of water andcause disease because the unbalanced interaction between host and pathogen environment. One of the types ofpathogens that often attract crabs are a parasite. The purpose of this study was to determine the prevalence andintensity of ectoparasites on mangrove crab (Scylla serrata) that were caught in coastal of Kenjeran, Surabaya.Parasite examination performed in the faculty laboratory. This study used survey method. Sampling was donerandomly. Data were analyzed descriptively in the form of table and figures. The study showed that theectoparasite found were Zoothamnium sp. with the prevalence of 2.27%, Octolasmis sp. with prevalence of 80%and mixed infestation (Zoothamnium sp. and Octolasmis sp.) with prevalence of 6.67%. The total value ofectoparasite prevalence was 97.78%, included in the category almost always infestation mud crab (Scyllaserrata). Zoothamnium sp. intensity value for 9.5 parasite / mangrove crab including in the very mild categoryand Octolasmis sp. intensity value for 149.23 parasite/ mangrove crab, including the very heavy category.Water quality measurements showed sea temperature ranges 22-25oC, pH 7-8, and dissolved oxygen 4-6 mg/l.
